Daniel McDonald 35efe68ba7 add simple input validation on gorm.Open function (#1855)

and, if not, early return with error.

Russ Egan 45f1a95051 Replace all use of *sql.DB with sqlCommon 
Exporting sqlCommon as SQLCommon.

This allows passing alternate implementations of the database connection, or wrapping the connection with middleware.  This change didn't change any usages of the database variables.  All usages were already only using the functions defined in SQLCommon.

This does cause a breaking change in Dialect, since *sql.DB was referenced in the interface.

slockij e26cb8dbc4 In some cases (Error not checked, missed data) one can perform very harmful operation - global update or delete (all records) 
This is to prevent it.

Make gorm.Errors available for use outside gorm 
gorm.Errors, which usefully implements `error` for an `[]error` as
returned by `DB.GetError()` was already exported, but because it used a
private field `errors`, it was not able to be created due to the
compile-time error:

    implicit assignment of unexported field 'errors' in gorm.Errors literal

The trivial solution would be to export the `errors` field on
`gorm.Errors`, but this led to the issue that the common pattern of
checking `err != nil` failed because a struct{error: nil} != nil.

We can take advantage of type aliasing here to make Errors an []error,
which can in fact be nil and would pass `err != nil` on the happy path.

* Remove `(Errors) GetErrors()`, as it's less useful when Errors is an
  []error which can be iterated over. While this is technically a
  breaking change, we never expose an Errors and its difficult to build
  one (it can be done with the existing `(Errors) Add(error)`), but
  awkwardly. This removal can be reverted without issue and we can make
  it an identity method, but it seemed an opportune time to reduce API
  surface area on something that likely isn't used.
* Remove errorsInterface, as it's not useful without `(Errors)
  GetErrors()`
* Change `(*Errors) Add(error)` => `(Errors) Add(error...) Errors`
  because we can't modify even a *Errors when it's a type alias. This is
  more idiomatic as it follows the pattern of `slice = append(slice,
  element)` Go developers are familiar with.
